Brachystylus

Brachystylus has hitherto included a single species only, B. acutus (Say), from North America; the two from Mexico now added are perfectly congeneric. They have a short broad rostrum, with short, superior, posteriorly converging scrobes, the latter connected behind with a shallower, obliquely descending, densely squamose groove; the antennal scape short and stout; the eyes small and very widely separated; the elytra 10-striate, the outer striæ coalescent at about the basal third; the legs short and stout; the posterior tibiæ laminate and squamose at the apex, and with the articular surface short and terminal; the anterior tibiæ denticulate and unguiculate; the tarsal claws free; and the body winged and densely squamose. This genus must be placed near Compsus. The free tarsal claws separate Brachystylus from the Phyllobiina.
